Downlink Massive MU-MIMO with Successively-Regularized Zero Forcing Precoding [PDF]
IEEE Wireless Communications Letters, 2022 In this letter, we consider linear precoding for downlink massive multi-user (MU) multiple-input multiple-output (MIMO) systems. We propose the novel successively-regularized zero forcing (SRZF) precoding, which exploits successive null spaces of the ...

Local Partial Zero-Forcing Precoding for Cell-Free Massive MIMO [PDF]
IEEE Transactions on Wireless Communications, 2020 Cell-free Massive MIMO (multiple-input multiple-output) is a promising distributed network architecture for 5G-and-beyond systems. It guarantees ubiquitous coverage at high spectral efficiency (SE) by leveraging signal co-processing at multiple access ...

Optimization of the Receiving Orientation Angle for Zero-Forcing Precoding in VLC [PDF]
IEEE Communications Letters, 2020 We study the performance of linear zero-forcing (ZF) precoding in multiuser multiple-input single-output visible light communications (VLC) when we are able to select the receiving orientation angle (ROA) of each user. For radio-frequency communications,

Experimental Investigation of TDD Reciprocity-Based Zero-Forcing Transmit Precoding [PDF]
EURASIP Journal on Advances in Signal Processing, 2011 We describe an implementation of TDD reciprocity based zero-forcing linear precoding on a wireless testbed. A calibration technique which self-calibrates the base-station without the need for help from other nodes is described. Performance results in terms of downlink channel estimation error as well as bit error rate (BER) and signal to interference ...

Improved Iterative Inverse Matrix Approximation Algorithm for Zero Forcing Precoding in Large Antenna Arrays [PDF]
IEEE Access, 2022 Precoding algorithms are used in massive multiple-input multiple-output (mMIMO) communication systems to ensure effective signal transmission. The zero-forcing (ZF) is one of the most common linear precoding algorithms used in MIMO and mMIMO systems.

Deep Learning-Aided Delay-Tolerant Zero-Forcing Precoding in Cell-Free Massive MIMO [PDF]
IEEE Vehicular Technology Conference, 2022 In the context of cell-free massive multi-input multi-output (CFmMIMO), zero-forcing precoding (ZFP) is superior in terms of spectral efficiency. However, it suffers from channel aging owing to fronthaul and processing delays. In this paper, we propose a

Zero-Forcing Precoding and Generalized Inverses [PDF]
IEEE Transactions on Signal Processing, 2008 We consider the problem of linear zero-forcing precoding design and discuss its relation to the theory of generalized inverses in linear algebra. Special attention is given to a specific generalized inverse known as the pseudo-inverse. We begin with the standard design under the assumption of a total power constraint and prove that precoders based on ...

Energy Efficiency in Cell-Free Massive MIMO with Zero-Forcing Precoding Design [PDF]
IEEE Communications Letters, 2017 We consider the downlink of a cell-free massive multiple-input multiple-output (MIMO) network, where numerous distributed access points (APs) serve a smaller number of users under time division duplex operation.
